HDAC9 (Histone Deacetylase 9)

Additionally, a higher throughput thermal shift format was developed using dot blot analysis. Thermal shift analysis offers a useful complement to enzyme activity assays for characterization of HDAC inhibitors.

Although current evidence for altered HDAC9 expression in this disorder is confined to the placenta, its potential role in maternal physiology remains an open and important question. By integrating findings from placental biology and disorders with overlapping pathways such as cardiovascular disease and cancer research, this review aims to establish a framework for understanding how HDAC9 contributes to preeclampsia pathogenesis and to identify promising directions for future investigation and therapeutic development.

This study highlights the need for rigorous validation of results. In our case, two orthogonal testing methods were not sufficient to catch all the confounding factors involved in measurement of HDAC inhibition, and a third approach was required to identify the actual inhibition of 9 against HDAC9 and 11.

High-risk patients exhibited poor survival, enhanced immune infiltration, and potential sensitivity to AKT inhibitors, with several drugs, including gefitinib and paclitaxel, identified as promising candidates. Additional prognostic genes (DFFB, PSMB6, GLP1R, HDAC9, BACH2) displayed expression patterns largely consistent across HPA, TCGA, and RT-qPCR, with minor discrepancies likely due to sample size. This study integrates multi-omics and deep learning with experimental validation, providing insights into programmed cell death regulation and offering robust biomarkers and therapeutic targets for GC.

Our study demonstrates that TUT4-mediated elevation of the miR-92b-3p/-5p ratio promotes COL7A1 transcription via silencing HDAC9 and alleviation of FOXP3 targeting, leading to collagen deposition and heightened TMZ resistance. Our results suggest that targeting miR-92b strand selection may serve as a potential therapeutic strategy for sensitizing GBM to TMZ.

Furthermore, patient profiling based on the epigenetic state of the super-enhancers controlled by HDAC4 successfully identified a priori CRC patients resistant to platinum. This study supports HDAC4 as a key mediator of oxaliplatin resistance in FBXW7-mutated CRC and highlights the remodeling of a well-defined super-enhancer repertoire as part of the process of OXPT resensitization.

Their prognostic value remained significant after adjusting for copy number alterations and transcriptomic subtypes. A 4-feature model integrating these two promoter activities with two clinical variables (Tumor size, Ki67 index) achieved an AUROC of 0.73 and improved patient risk stratification, with a Net Reclassification Improvement (NRI) of 0.40-0.48 over the clinical-only model, underscoring the potential of promoter activity as a biomarker in TNBC.

Furthermore, this compound's effectiveness and safety were confirmed in both MH/NRASG12D BCP-ALL mouse model and MB patient-derived xenograft (PDX) model, outperforming conventional therapies. These results support the therapeutic potential of dual-pathway inhibition in MEF2D fusion (+) BCP-ALL and suggest CUDC-907 as a promising candidate for precision treatment in fusion-driven leukemias with similar molecular dependencies.

Two OSCC subtypes and eight prognostic genes (TGFBR3, CYCS, HDAC9, PLK1, GSDMB, HSPA4, BAK1, SOD2) were identified, aiding in treatment and risk stratification. BAK1 is causally linked to OSCC risk.

Confirmation of in vivo efficacy was pursued in several animal models, with subsequent molecular-correlate derivation confirming the importance of MYC depletion and mitochondrial dysfunction in drug efficacy. Ultimately, we define a therapeutic approach combining MYC- and class IIa HDAC-inhibition to potentiate anti-tumor efficacy in NSCLC.

Our findings emphasize the importance of targeting key signaling pathways in melanoma CSCs and underscore the value of mimicking the tumor microenvironment in experimental models. By revealing the dynamic plasticity of melanoma CSCs, this study offers fresh insights into potential therapeutic strategies, particularly using siRNA to modulate pathways associated with tumor progression and stem cell behavior.

Collectively, our results demonstrate that HDAC9 promotes EndoMT by regulating ANXA2 transcription, thereby disrupting vascular homeostasis during DR. This study sheds light on the roles of HDAC9 and ANXA2 in DR pathology and provides a theoretical foundation for the potential therapeutic strategies to target DR.
